同(tong)步帶輪(lun)T5型(xing)由輪(lun)緣、輪(lun)輻和輪(lun)轂三部分組(zu)成。設計帶輪(lun)時，應使其結構便于(yu)制造(zao)，質量分布均勻，重(zhong)量輕(qing)，并避免由于(yu)鑄(zhu)造(zao)產生過大的內(nei)應力。

當(dang)(dang)V>5m/s時進(jin)(jin)行(xing)靜平衡，當(dang)(dang)v > 25m/s時進(jin)(jin)行(xing)動(dong)平衡。同(tong)步(bu)帶輪(lun)材料中常用(yong)(yong)(yong)灰鑄(zhu)(zhu)鐵、45#鋼、鋁(lv)合金、銅或(huo)工程塑(su)料。灰鑄(zhu)(zhu)鐵應(ying)用(yong)(yong)(yong)廣泛，當(dang)(dang)V≤30m/s，V ≥ 25 ~ 45m/s時使(shi)用(yong)(yong)(yong)HT200。則宜選用(yong)(yong)(yong)創(chuang)造(zao)生鐵開(kai)鑄(zhu)(zhu)鋼件，也能用(yong)(yong)(yong)厚鋼板沖(chong)壓模具一電(dian)焊(han)焊(han)接(jie)同(tong)步(bu)帶輪(lun)。小輸出功率(lv)傳動(dong)系統能夠(gou)用(yong)(yong)(yong)鋁(lv)鑄(zhu)(zhu)和塑(su)膠(jiao)。
